Thomas H. BRADY, or NEW 'nnxrstrig oonitnei icn's PULL-SQCKET.

of New'llrituin, in the county of Hartford.

and State of (li onnecticut, have invented certain new and useful Improvements in Pull- Soclcets, of which the following is a specifi. cation.

The object of the invention is to produce a device of the character described having features of novelty and advantage and has particular reference to the construction of the operative parts for the movable member.

Referrhig to the drawings1*igure l is a invention with arts broken away to. show construction? Fig-Z a detail side elevation of the some with the shell removed and arts broken away to show construction. ig. 3 is a plan view of the operating member for the movable contact. Fig. 4 is a side View thereof. Fig. 5 shows in central vertical sectionthe driving connection between the operating nember rind the movable contact. rig. (to; a plan view oi the base. Fig. 7 is a plan view of the rotating member of the driving connect-ion. Fig.8 is a detail side elevation of the driving connection, parts being broken away to show the opero tion of the device.

Referring to the drawings a isthe shell having an insulating lining I). 'ithin the shell are located-u pair of insulatin' blocks 1l0, connected together-lav suitabl e struts or standards 15-16. The upper surface-of the lower insulating block 10 is provided with four inclines, indicated at 11, each terminating in an abru t shoulder 12'; one bf the inclines has :1 meta plate 13 electrics-l1yv connected -With one of the stendardsx lii, which is provided with a bindingescrew It? the otlier'standard 16' is in electrical contactwith the shell 18 of a. limipweceiving socket ofusual construction and is provided with a b1ndlng;screw 10. Supported between the u )pernnd lower insulating blocks is a spin- ,;dle 20, its upper end being centered in a. recess in it cup :21 which is located in the under side vof the upper insulating block 1.

F xedly secured to this spindle is a drivin member 30 having integral pins :37 whici assthrggghg-thehub of an operating memer an Titre then bent down to secu'rethe I operatingimember to the driving, member.

In the ebuttin surfaces of==the driving is 3050 are recesses 31 *51 having oppositely dis osed shoulders i-l3-53'betwe-.;nj which a bal is engaged to complete the driving connection between the two ports w rot-uted'in, one motion.
